Abstract :
A time measurement circuit based on the principle of the multiple-phase oscillator is presented. The multiple phases are realized with a delay line ring oscillator, resulting in a compact, simple structure. The circuit is implemented in 5 V, 1.2 um CMOS process. The measured single-shot resolution is 1.5 ns (sigma-value) and the maximum measured error is 4 ns in the measurement range 5 ns -10 us with temperature variation between -40 to +60°C and supply voltage variation between 4.5 and 5.5 V. Nominal current consumption is 2.5 mA
